+[* 1] Once Step 1 has been completed, the autotensioner can be installed. Figure 2b shows the 45 mm M8x1.25 bolt being inserted into the top of the autotensioner. This bolt should thread into the hole that the upper alternator bolt originally went into.
+[* 1] Figure 2c shows the 20 mm M8x1.25 bolt being installed in the lower mounting hole on the autotensioner. This bolt should thread into the left lower hole that the alternator was originally mounted to. Both bolts can be tightened using a 6 mm allen driver.
+[* 1] Torque both M8 bolts to 35 lbft (dry) or 28 lb-ft (lubricated with oil). Failure to properly torque bolts can result in premature fatigue or loosening of the bolts. (Note: color of bolts may vary)
+[* 1] One of the unique features about this autotensioner is that it’s designed to use different belt sizes without compromising performance by maintaining proper belt tension through an adjustable spring housing.
+[* 1] Figure 2d shows the 3 bolts that must be removed to adjust the spring housing. The bolts are an M8x1.25 thread and can be removed using a 6mm allen driver. Figure 2e shows the parts that should be loose once the spring housing has been removed.
+[* 1] Shown from left to right is (1) spring housing, (1) bolt backing plate, and (3) M8 bolts and M8 lock washers. Torque all three M8 bolts to 35 lb-ft (dry) or 28 lb-ft (lubricated with oil). Failure to properly torque bolts can result in premature fatigue or loosening of the bolts.
+[* 1] The autotensioner is supplied in its lowest position. Figure 2f shows how no open grooves are visible at the lower portion of the autotensioner. Figure 2g shows the autotensioner adjusted to its highest setting, where 4 grooves are showing. In the case of a k24, typically 2-3 grooves will need to show if the supplied belt is used.
+[* 1] In the case of a k20, typically 3-4 grooves will need to show if the supplied belt is used. The supplied belt is a 48.5” long 6-rib belt. Note that between the lowest and highest settings, there is enough adjustment to compensate for about a 2” variation in belt length. This allows some flexibility when it comes time to replace your belt.
